Random observation: I'm willing to bet that the fact that Marvel went with a non-marquee TV star to be Cap's love interest means it's likely that Vancamp was signed to a multi-pic deal. They have a history of recruiting TV stars for recurring roles, while going for known-quantity names for one-shot villains and supporting cast. If true, Agent 13 might well show up in *lots* of places, including the SHIELD TV show.
